From MSNBC "In Tokyo, the best advice experts could give residents was to stay indoors,
close the windows and avoid breathing bad air -- steps very similar to those for handling a smog alert or avoiding influenza"

Ummm yeah and hey if that don't work (cuz radiation won't go through glass???)...put on your tin foil hats.

Actually dustbowl, depending on the specific airborne contaminant, the radiation won't go through glass. The radiation from a particle that decays through alpha or beta particle emission won't go through glass. Alpha emitters won't penetrate the outer layer of skin and are only a concern if ingested. Beta emitters can easily be shielded by a layer of clothing.

Many of the radionuclides in a contamination plume are beta emitters - the advice to close up windows and secure ventilation is very sound advice for people who can't leave.

Hi and Thank you for sharing with us what you know, it is greatly appreciated.
My brother lives in Fujiyoshida Japan; he sent me an email he received from Yamanashi Prefecture.
Here is the link if you would like to see it from the actual website; http://www.pref.yamanashi.jp/english/news/PowerOutage.html
It is telling them the power outage schedule and power conservation. My question to you is the information they give at the very bottom on Radiation Levels in Yamanashi, what is your belief on its accuracy? I copied it and pasted it below.

Thank you,
xoxo :)

Updates on Radiation Levels in Yamanashi Prefecture
Yamanashi Prefecture is commissioned by the Ministry of Education, Culture, Sports, Science and Technology, and has been monitoring the radiation levels in the prefecture using the Monitoring Post installed at the Institute for Public Health and Environment (Fushimi in Kofu City).
According to the observation , the radiation levels since the Fukushima nuclear accident have been ranging from 0.04~0.06 micro sievert per hour (μSv/h). The following is a record on the most recent measurement of radiation in Yamanashi Prefecture.
Date Time Radiation Dose Measured Unit
03/15 5pm 0.058 μSv/h
03/16 9am 0.045 μSv/h
03/16 1pm 0.045 μSv/h
The detected radiation levels do not raise health concerns.
They fall within the radiation range recorded in Yamanashi Prefecture in the past (recorded range: 0.04~0.06 micro sievert per hour)
【Reference】
1.Radiation Dose Measurement(per hour)
Radiation levels indicate the amount of radiation released per hour. For example, a radiation level of 0.050μSv/h would be [ 0.050(μSv/hours)×24(hours)×365(days)=approx. 440(μSv/year)]
2. Radiation Exposure in Daily Life・・・For more information, please click here or here. (Information from the Ministry of Education, Culture, Sports, Science and Technology)
The reported average annual radiation exposure from natural sources for human beings is 2400 µSv. Radiation exposure from natural sources, or natural background radiation, comes from space, earth and food.
For your reference, the radiation exposure is 50μSv for one chest X-ray checkup, 600μSv for one abdominal X-Ray checkup.
【Radiation Levels Update Frequency】
Yamanashi Prefecture has been commissioned to measure the environmental radioactivity level in Yamanashi by the Ministry of Education, Culture, Sports, Science and Technology in Japan. We are not able to provide real-time updates on radiation levels. However, we will update 3 times a day on the newest radiation levels in Yamanashi. Thank you for your understanding.

However, if the radiation level is above 0.1μSv/h1 (2 times more than the usual level), we will successively update the newest radiation level.

0.1μSv/h×24(hours)×365(days)=approximately 880(μSv/a year)・・・<1,000 (Regular radiation exposure per person in one year.)
*Please be aware that information on the radiation levels is a translation based on the Japanese version on the prefectural homepage. Please click here for the Japanaese version

:)xoxo -

The levels reported look consistent with other sites that have been reporting radiation levels. It looks like the levels are still around normal background levels. Make sure you write down the background levels each day and do a comparison. If airborne contamination does spread to your location, you might see a small increase from one day to next that doesn't appear to be out of the ordinary, but when compared to the initial readings will indicate slightly increased radiation levels. As long as the winds remain from the west, you should be fine, but keep an eye on the weather reporting.

I will try and find some links to real time monitors set up in various cities on Honshu.

Best of luck for you and your family.

Thanks mandojammer,
As an environmental radiochemist (& PhD in chemistry, not radiochem though), I must say that you are right on the mark.
I also suggest again that those of us who pray do so & do so frequently & that those of us who don't tolerate those of us who do through this time. Perhaps check with your favorite charity or religious institution to see if you can volunteer or donate in some manner.

With Love,

PS One of the sites that I've been refreshing regularly is

http://www.nei.org/newsandevents/information-on-the-japanese-earthquake-and-reactors-in-that-region/

sadly it is reporting in part:
"UPDATE AS OF 5:45 P.M. EDT, WEDNESDAY, MARCH 16:

U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko told members of Congress today that there is no water remaining in the fuel pool at reactor 4 at Fukushima Daiichi nuclear power plant. Jaczko told members of the House Energy and Commerce Committee that “we believe that secondary containment has been destroyed and there is no water in the spent fuel pool…radiation levels are extremely high, which could impact the ability to take corrective measures.”"

There is no updated information available from either Tokyo Electric Power or Japanese safety or regulatory officials on the status of the Fukushima plant. Japan's Nuclear and Industrial Safety Agency said it also is concerned about the spent fuel storage pool at reactor 3 at the Fukushima Daiichi site.

I hope & pray that this is good news:

from the NEI link above:
UPDATE AS OF 9:00 P.M. EDT, WEDNESDAY, MARCH 16:

***...Spokesmen for TEPCO and Japan’s regulatory agency, Nuclear and Industry Safety Agency, on March 17 Japan time refuted reports that there was a complete loss of cooling water in the used fuel pool at Fukushima Daiichi reactor 4. ...***
Recent radiation levels measured at the boundary of the Fukushima Daiichi plant have been dropping steadily over the past 12 hours, Japan's Nuclear and Industrial Safety Agency said on Wednesday night (U.S. time).

At 4 a.m. EDT on Wednesday, a radiation level of 75 millirem per hour was recorded at the plant's main gate. At 4 p.m. EDT, the reading at one plant site gate was 34 millirem per hour. By comparison, the Nuclear Regulatory Commission’s annual radiation dose limit for the public is 100 millirem. Radiation readings are being taken every 30 minutes."

This is almost 3 orders of magnitude lower that earlier reports & this is very good!

What's appearing very sad to me is how this is playing out right now. TEPCO (Tokyo Electric) appears to be acting the same way as BP did with the Gulf of Mexico oil leak disaster.

Yep, the Ostrich Syndrome. Deny and stick your head in the sand, hope nobody will see you.
